In short, while "girlboss" was meant to mean "strong woman", over time it came to mean "entitled, mean woman with power". Some, mainly the left, still try to get the term back to its original definition but they have largely given up as normies tend to associate it with cringe and bad storytelling with unsympathetic characters. Thus, barring exceptions, it has fallen out of use. No one on their right mind would refer to Beatrix Kiddo/Ellen Ripley/Sarah Connor as a "girlboss" today. It is too tainted.
In short, girlbosses are just Mary-Sues who are specifically intended to be women.
About the culture war stuff, I generally find competent female combatants appealing because I just like the idea of characters being cool.
Returnal seems to be alright, that is if you like your bog standard roguelike shooter in third person with AAA quality and budget. If you're asking if it's worth buying a PS5 for, no.
Returnal itself does seem interesting, but indeed it's not a system seller, and while Sony fanboys will speak positively about the game, they never really do prove themselves to genuinely enjoy the game, since they're more interested in sports games, movie games, or as who I'm about to mention prefers, multiplat games. Playstation exclusives that don't play like a third person cover shooter with extensive walking and talking segments are just opportunities to show their loyalty to Sony.

Meet one of the typical Sony fanboys, Xvault Gaming, or as I would like to call him, Baldin Hood of Norwood Forest. Despite trying to build an entire Youtube career on talking shit about Xbox and PC gaming and calling others grifters, he is unable to think of streaming anything other than Marvel Rivals, which is available with crossplay on multiple systems. He and his crooked nose tries so hard to rely on appearing correct by putting on a smug face and appearing confident until whatever claims or arguments he makes in Sony's favor turn out to be true.

Except every single one of his
thumbnails to look like this, with him making the same face and rubbing his chin like it's a genie's lamp. Even if Xbox sucks, one should know and remember that this guy bought not only one, but two, but three PS5s, just so he can coerce his wife and son to play Concord with him, of which he bought not one, but two, but THREE copies of. THREE PS5s and THREE copies of Concord.
People like these don't actually care about games like Returnal, or Gravity Rush, or Pataon, or anything that didn't come out of a western AAA company's ass. They're mostly here because they think that the Playstation's price makes ownership a stockholder-level investment and a pass to a secret club, nevermind the fact that PC gaming has a potentially similar (initial) hardware cost and is technically more difficult to get into. If they aren't wannabe Apple cultists, then they're just niggers and wiggers pretending at being professional podcasters, unaware that they're the same genetic stock as Darksydephil.
